Abstract
A composite-part manufacturing method comprises placing a bladder against a trough surface of a tool that has a tool radius portion elongating between the trough surface and a major surface of the tool, and placing a radius filler in vicinity of the tool radius portion. The method also comprises applying a peel-away ply over the radius filler, and applying at least one material layer on the peel-away ply. The method further comprises after the at least one material layer has been applied on the peel-away ply, moving the peel-away ply away from the bladder and the major surface of the tool and thereby to move the radius filler along with the peel-away ply away from the tool radius portion to form a composite part having a smooth join surface in vicinity of the tool radius portion.
